The invention relates to a marine integrated electric steering engine. The marine integrated electric steering engine is characterized by comprising a planetary roller, a screw, a permanent magnet rotor, a stator winding, thrust bearings, and a displacement sensor. The screw, the planetary roller and the permanent magnet rotor form a linear transmission pair form inside to outside. The linear transmission pair is disposed inside a barrel formed by the stator winding and an electric steering engine cylinder. Two ends of the permanent magnet rotor are disposed between the electric steering engine cylinder and the stator winding through the thrust bearings. The screw extends out of an inner cavity of the electric steering engine cylinder. The displacement sensor is disposed between the screw and the electric steering engine cylinder. The marine integrated electric steering engine with no reduction mechanism is more compact in structure, high in reliability, well mute, efficient, and easy to control.
Description
technical field [0001] The invention relates to a marine integrated electric steering gear, in particular to a high-power integrated electric steering gear. Background technique [0002] As an important equipment to ensure the safe navigation of ships, the steering gear has high requirements for its reliability. The traditional electric steering gear of a ship is mainly composed of a motor and a reduction mechanism. Through the reduction mechanism, the rotational motion of the motor is converted into the linear motion of the push rod to achieve a driving effect similar to that of a hydraulic cylinder. However, due to the wear and tear of the deceleration mechanism, the traditional electric steering gear has many recognized defects in terms of reliability, propulsion efficiency, maintainability, etc., and cannot work with heavy loads for a long time. The problem has become a weak link in the technical development of ship steering mechanism. Contents of the invention [00...
